Be it known that I, FREMAN N. CORBIN, ot Gheulplain, in the county of Clinton, and Stnteof'New York,

here invented n. new and improved Evener; and I do hereby declare that the fol-lowingis mfull, clear, and exact description thereof, whiehwill enable those skilled in the art to makeand use the seule, reference being had tol the accompanying drawings,forming port of this'specioetion.

'This inv ention relates to a new and im'proved application of a double-tree to thedraught-pole of a. wheelvehiele, es hereinafter fully shown nud described, whereby the olevises 'to which thel wl'lile-trees are attached will be shifted laterally, one being brought nearer to the draught-pole as the other is'mo'ed outward'fi'om it, so Y that the most ambitious or the strongest-pulling horse, Wheuevenhei exerts ,himself more than the other, will have his leverage poweron tire double-trce decreased, while at `the sametimelthe leverage power of' the other horse will be propertionebly increased.

`By this arrangement a team will soon be mode -to pull evenly withoutau'y special care-onnttentionon the part of the driver. In the accompanying sheet of drawings- Figure lis e plan or top view of my invention. Y

Figure 2 a. side sectional view ofthe seme, taken inthe line :t z, fig. 1.

Similar letters of reference indicate corresponding parts.

A. represents a. draught-pole,.andB n double-t`ree,zitt'o.ched-thf reto by a. bolt, ,t, ,whicl1 vbolt passes through the front end of a. metal plete, C, the rear end of the lutter being fitted .on' n. hook, D, attho rear' part of the The double-trceB has two oblong notches, b d, made in its rear-side, one near each end, and-these notches are covered by metal plates e c, which are bolted to the rein' sidetoi` the whiille-tree,ras shown et d, fig..1

E E represent two hars, the rear .endsvof `which lare zitt'nched-by o. pivotbolt, e, tothe under side ofthe roar* part ofthe plete C. i o

A The front ends of the bars E are gunde in the form offorks, aud to their forked ends clevisesF F are attached,

^ byibolts f,l and these bolts pass through the oblong notchesib @und 4are allowed to slide freely therein. o

The whiiile-trees are attached to the clevises F F. l V o t 'By this arrangement it will be seen that when one horse pulls more than the other, the end of the double- Vtreoto which the strongest-pulling yhorse is attached will .be drawn forward, und the clevis at the forward end of the double-tree moved towards the draught-pole, while the 'otherelevis will be moved outward therefrom, 'wi-1; the weaker horse the greatest leveragel power', and causing him to-m'ove forward-in liuc with the n'er one.

This automatic arrangement will .soonA cnusea. teem to pull4 evenly, however irregular they may be in their draught-action when first vattached to .the vehicle.

I claim as new, nuddesire to .secure by Letters Patentv t rlhe combination ofthe double-tree B,elevises F F,bars E E, all arranged and applied to the draught-pole A, to operate iu the'mnnner substantially es and for the purpose set forth. Y i i The above speciieetion of my invention signed by ine, this 19th dey of February, 1868. l
